TIRE CASING.

Application filed October 16, 1922.

To all whom it may concern:

Be it known that I, Flinn L. LA Tour, a citizen of the United. States,residing in the city or": Los Angeles, county of Los Angeles, and Stateof Californimhave invented certain new and useful Improvements in TireCasings, of which the following is a specification.

My invention relates to tire casings, and more particularly to the useof a material for reinforcing and building up the body of saidcasinginvolving a new mode of construction and resulting in a superiorfinished article. I have foundby experiments that rawhide can be used inthe construction of tire casing and if used in accordance with my modeof construction will make amost effective reinforcement for a tirecasing and one which will wear much longer than will the materials nowused. In developing my mode of construction, I have taken strips ofrawhide of sufficient width to be perforated or punched with smallopenings therein and have placed them diagonally around the easing, fromone side to the other, at a space apart, so as to leave a narrow spacebetween each strip, then applying a layer of rubber composition, andthen applying another layer of rawhide strips diagonally in the oppositedirection over the first layer, and applying another layer of rubber, orother suitable composition, and then applying a third layerof strips ofrawhide in the same general diagonal direction of the first layer ofstrips, but shifted circumferentially of the tire so that each stripwill overlie the space between the two strips thereunder, thus coveringthe entire area with the three or more layers of rawhide, with rubbercom position between and through the strips, and

forming the tread of the tire casing.

In order to more clearly explain my invention, I have illustrated oneembodiment thereof on the accompanying sheet of drawings, which ll willnow describe. In the drawings,-

Figure 1 is a cross sectional view through a tire embodying theinvention; and

F igure 2 is a top plan view, showing the different layers.

Referring now to the drawings in detail, the innermost layer of the tirecasing can be made of any suitable fabric material, and is designated 1,over which. is laid a layer of Serial no. 594,767.

strips of rawhide, 2, 2, each shown perforated, tween each two strips.0ver this la *er of rawhide strips is placed a layer of rubbercomposition, designated, 5, which fills the spaces 4, and also theperforations, 3. Over this layer of rubber composition, in the oppositedirection, is a second layer of rawhide strips, 6, 6, perforated, as at7, 7, and that is covered with a second layer of rubber composition, asindicated at 8. Over this second layer of rubber composition is placed athird layer of rawhide strips, 9, 9, also perforated, as at 10, 10.These strips are so placed that they overliethe spaces, a, in the firstlayer of rawhide strips, as indicated by the dotted lines in Fig. thuscovering the entire area with the'strips of rawhide and not leaving anyradial opening, or uncovered spot, through which a sharp article mightpass to the interior of the casing.

The outer, or tread, portion of the casing is bullt up in any desireddesign, and to any desired extent, as at 11, with the rubbercomposition, or any other suitable tread material. The strips of rawhideare of sufiicient width to be perforated and of sufficient length,preferably, to extend from one edge of the tire over to the other, andsome of them can be turned around the heels, 12, of the tire casing, asillustrated and thus the whole structure is vulcanized into onehomogeneous casing body, the strips of rawhide being kept suflicientlyseparated from each other as not to cut or wear one upon the other andbeing protected so as to maintain their desirable flexibility andtoughness.

I am aware that changes can be made in the general arrangement ofrawhide strips as a reinforcing means for tire casings with outdeparting from the spirit of my invention, and I do not limit myinvention to the particular showing made for illustrative as at 3, 3,and with the space, l, be-.

purposes, except as I may be limited by the 7 I between, said layers ofrawhide being 2.
